Question

下午好，

我有一个问题，我已经拖延了几天，似乎无法理解我的意思。只是想知道是否有人可以指出我正确的方向。我在用着： -Laravel版本：5.8。 -PHP版本：7.2.5 -数据库驱动程序和版本：mysql 有什么建议我做错了吗？感谢您的答复！

Stacktrace：

这是我的018_07_18_054859_create_counters_table.php代码

<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateCountersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('counters', function (Blueprint $table) {
            $table->increments('id');
            $table->string('key')->unique();
            $table->string('prefix')->unique();
            $table->integer('value');
            $table->timestamps();
        });
        $this->load();
    }

    protected function load()
    {
        DB::table('counters')->insert(config('crm.counters'));
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('counters');
    }
}

传递给Illuminate \ Database \ Query \ Builder :: insert（）的参数1必须为数组类型，给定null
